really weathered.but tread is still good.can I put an
Inertube. ,like the good ole days.also they don't
make regular gas.anymore.should I continue to
add gas treatment and adatives?
Tubes can't be used in a radial tire. You would have to switch to a different type of tire. (At which point you would probably be better off just getting a new set of radials.) You should also keep adding an additive to the engine as it will keep the valve seals in good shape on modern gas, or get the heads rebuilt with hardened valve seats.
16 1/2" tires are an old style tire size. I might switch to a more modern wheel such as 16" or 17". You can get 16 1/2" innertubes that are rated for radial tires.
